SELF-ADJUSTING DUMP BUCKET'.

Specification of `Letters Patent. i Faisant-.Qd- Aug, 89:1922

Application led Eecember 2, 1920. Serial No. 427,894.

To @ZZ ifi/1.0m it may concern.'

Be it known that i, GEORGE `W. SLAUTER, citizen of the United States, residing at Dixon, in the county of Lee and State of Illinois, have invented certain new and useful improvements in Self-Adjusting Dump Buckets, of which the following is a speci.- iication.

This invention relates to certain new and useful improvements in buckets, and it has more particular relation to that class of buckets known as hoisting or excavating buckets. j

One of the objects l have in view, is to provide a bucket for removing earth, rock or other material Yfrom one point to another', the bucket being so constructed that upon its being lowered to the ground or other suitable support, its bottom, consisting of two hinged sections, automatically` falls apart and permits the load to be discharged.

Another object of my invention, is toprovide means whereby when the bucket has discharged its contents, and is being raised,

its two hinged bottom sections will automatically close, and upon the 4arrival of the bucket at the loading point, it will be ready to be refilled, without requiring the services of some one to adjust and lock its hinged bottom sections.

Vith these and other objects in view which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary -elements comprising my invention, may be varied in construction, proportions and arrangement, wthout departing. from the spirit `and scope of the appended claims.

In order to make my invention more clearly understood, I have shown in the accompanying drawings means Jfor carrying the same into practical eiect, without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

Figure 1 is a side elevation of myfdevice Vshowing the bottom sections of the bucket closed'.`

, Figure 2 1s an end. view thereof.

I f 'Figure'B is also an end view showing the bottom vsections open;

, Figurev 4 is a side view showing the operativemechanism for opening and closing the botto-m sections as it appears when the sections are open. n

Figure 5 is a similar view showing said mechanism as it appears when the sections are closed, and

Figure 6 is a detail viewv of one of the track wheels, upon the sides of the bucket.

Numeral 1, refers to the body of a bucket, made vof metal or other suitable material and of a more or less rectangular configuration., The numeral 2, refers to two hinged sections which together form the dumping bottom.. These sections are provided with hinges 3 8. secured thereto-by bolts or rivets 4-4 and also to the sides of the bucket by similar bolts or rivets 5-5.` The attachment of the hinges is such, as to permit the swinging towards each other, of the two sections until they assume the closed position shown in Figures 1 and 2, or to open outwardly into the position shown in Figure 3.

The bucket is provided above the top of the body with a suspension yoke 6 to be hereinafter` more fully described. This yoke is secured to the upper end oi' arms 8, by rivets 9, and the lower ends of said arms, extend somewhat further apart, as they approach the bucket, and are securely riveted thereto by bolts 10.

As seen in Figures l, 2 and 6 the sides ofl the bucket are provided with brackets `consisting each of a bent metallic plate or casting 11, rigidly secured to the bucket by ybe referred to. The purpose of these wheels is to enable the bucket to be run on a track, (not shown), which is arranged to guide the bucket when lowered on it to a position to one side from a perpendicular line under the suspended trolley or other hoisting device and supporting the bucket under a suitable discharge trough or opening leading from a hopper, bin or other arrangement from which the bucket receives the material to be moved.

j On each side of the upper edge 18, of the bucket and between the arms 8, is mounted aplate 20, securely fastened thereto'by rivets or bolts 21. The upper central portion of this pla-te is cut-away so as to'vfurnish supports 22 for a rod or shaft 23, Which is mounted therein.y y Upon the shaft is mounted an idler 24 over which passes the chain or cable 25. i

The hinged dump sections 2, are each provided-at a point nearer the'center line of the bucket than the sides with vvan angular coupling 26, rigidly secured to the outer edge 'of eachsection by a rivetor/bolt` 27. The upperv end of this couplingis provided with an eye 28, to which is tted one of the links of the lower members of the` vchain 25. -As 'Will bessen by reference to Figure "l, 'thesetvvo lower members become unitedv at a point belovv track wheel 17.' The sus en- Vsion yoke 6 consist-s of twov beams or cian'd nel irons 7, secured to the arms 8f4-8, v'by boltsor rivets l9,an'd 'secured to eachother by theend bar'29, "(s'eeFig. 5) rigidly secured theretol ,'byl the bbltsBO-.f4 Pivotally mountedl Within 'they yokethus formed and extending upwardly therefrom when the bucket is in closed position, as'seen in Fig'- ure 2, are bale ,levers 31,andto thev outer 4end 01":l each'isiastened by al clevis 32,l or in any vSuitable manner'one end of thechain or cable 25. The lower end'of thel chain being divided into two members, one at tachedto eachfof the bottom sections. V Each vofl these levers 31, .at its inner end isrprovided with alatch plate 33, which is bent downwardly at an anglefrom the lever,

at the appropriate time, as"hereinafter more fully set fortlnone ofthe p'aivls 34, pivotally mounted upon the beaml 7. Each of thesepawlsis held in position by .afchain `35',attached to ya trip lever y36 jpivotally mounted in angle irons 3'?, 'securel to the top ofthef'lframe 7, vby means of bolts 38.l Pivotally attached to 'each of these bale levers' '31,.' are connecting bars 39, the iai therendcf each' 'of )vhichis bifurcated and into thisvbifurcation"fitsand is secured by y ,bolt 40, what; term"'a` hanger 4.1. Near the top this hanger isa hole 42, by means of [which 'the bucket' and the mechanism y heretofore described, vissuitably suspendedv ,trom a trolley ybyY a] cable or. rope, as it travels'back and forth. in its'l .journey from point' of loading charge- The operation ofl device isl follovv's:
